SPECIFICATION forming part of Letters Patent No. 539,661, dated May 21, 1 895.

Application filed May 14, 1894- Serial No. 511,172. (No model.)

To all whom it may concern: a screw bolt 14, the outer end of said bolt being Be it known that I, ALEXANDER BAsTAM, bent into a handle 15, and its inner end enof Milwaukee, in the county of Milwaukee gaging a recess 16 formed in the under side and State of Wisconsin, have invented a new of the tube or pipe 4. 55

Having thus described my invention, what I claim, and desire to secure by Letters Patent,is

1. In a street sprinkler, the combination of a downwardly opening chamber or cavity to which the water is conducted from the water box or reservoir, a lid or cover arranged beneath the chamber or cavity, a plate interposed between the lid or cover and the opening of the chamber or cavity,said plate secured to the lid or cover so as to have a vertical swinging movement independent of said lid or cover, and means for adjusting the plate closer to or farther away from the opening of the chamber or cover, substantially as set forth.

2. In a street sprinkler, the combination, of a chamber or cavity to which the water is conducted from the water box or reservoir, a lid or cover arranged beneath the chamber or cavity, a plate interposed between the lid or cover and the opening of the chamber or cavity, said plate connected at its front end to the lid or cover, and an adjusting screw passing through the lid or cover and engaging the plate whereby said plate is adjusted closer to or farther away from the mouth of the chamber or cavity, substantially as set forth.

3. In a street sprinkler, the combination, of a pipe or tube adapted to be connected to the water box or reservoir, and terminating at its rear in a chamber or cavity, the under side of the pipe or tube having a semi-circular groove therein, a packing within said groove, a pivoted under lid or cover, and means for turning said lid or cover on its pivot, and holding it in adjusted position, substantially as set forth.

4. In a street sprinkler, the combination, of a pipe or tube connected to the water box or reservoir, and terminating at its rear end in a chamber or cavity, the under surface of said pipe or tube provided with a groove, a lid or cover beneath the mouth of the cavity or recess,,an adjustable plate between the lid or cover and the cavity or recess, said lid or cover provided with a groove in its top surface, a packing within this groove, and a packing in the groove of the under surface of the pipe or tube, substantially as set forth.

5. In a street sprinkler, the combination, of a pipe or tube adapted to be connected to a water box or reservoir, said tube provided on its under side. with a depending apertured lug, and terminating at its rear end-in a chamber or cavity, a lid provided at its front end with a recess adapted to receive the depcnding lug, and having apertured ears or lugs on each side of the recess, a pivot boltpassing through the registering apertured lugs, a screw-bolt passing through a threaded aperture to one side of the pivot bolt, and having its end engaging a recess in the pipe or tube, a plate interposed between the under lid and the cavity or chamber of the pipe, a screw connecting the front end of the plate with the lid or cover, and an adjusting screw passing through said lid or cover, and engaging the plate, substantially as set forth.

In testimony whereof I allix my signature in presence of two witnesses.
